Lub tswv yim npe no ua rau nws yooj yim dua kom paub tias Wi-Fi thev naus laus zis tshiab dua li lwm tus.
Wi-Fi 6 nta
Muaj ntau yam txiaj ntsig rau Wi-Fi 6 dhau Wi-Fi 5 (dua, 802.11ac, raws li koj tau paub) thiab cov laus dua:
Ceev nrawm
Wi-Fi 6 yog ze li peb zaug sai dua Wi-Fi 5, thiab latency raug txo los ntawm 75 feem pua. Nrog rau qhov siab tshaj plaws hloov ceev ntawm txog 10 Gbps vs Wi-Fi 5's 3.5 Gbps, koj tuaj yeem rub tawm cov apps thiab cov ntaub ntawv sai dua, kwj cov yeeb yaj kiab nrog tsawg buffering, siv ntau cov khoom siv hauv tib lub network nrog tsawg hiccups, thiab muaj sijhawm sib tham video nrog qeeb qeeb..
Nws yog ib qho tseem ceeb kom paub, txawm li cas los xij, txawm hais tias Wi-Fi 6 ceev yog qhov theoretically capped ntawm ze li 10 Gbps, nws tsis tau txhais hais tias koj tuaj yeem tawm mus yuav Wi-Fi 6 router thiab mam li pib rub tawm ntawm cov ceev. Tsis tsuas yog 10 Gbps tsis yog qhov tseeb niaj hnub nrawm vim muaj qhov cuam tshuam xws li kev cuam tshuam tab sis kuj yog qhov koj them koj tus neeg muab kev pabcuam rau, vim qhov ntawd yog li cas koj cov ntaub ntawv hloov pauv lub kaus mom raug teeb tsa.
